This year, the mass migration began three weeks earlier than last year, with a handful of walruses tagged by the United State Geological Survey heading to shore as early as Aug. 7. Then on Wednesday (Aug. 17), about 8,000 were spotted on or near a beach north of Point Lay, the Associated Press reported.

thebchuckster writes: The darkest alien world ever spotted by astronomers has been discovered in the outskirts of our galaxy.

"It's darker than the blackest lump of coal, than dark acrylic paint you might paint with. It's bizarre how this huge planet became so absorbent of all the light that hits it," David Kipping, an astronomer at the Harvard-Smithsonian Center for Astrophysics.

thebchuckster writes: The budding yeast lives on simple sugars, which it makes by using an enzyme called invertase to chop more complex sugars, like sucrose, into smaller ones, such as glucose and fructose. But because most of these simple sugars escape by diffusing into the surrounding environment, the yeast cell can't consume all the food it makes.

Koschwanez and his team compared the success of single, isolated yeast cells (Saccharomyces cerevisiae) in a low-sucrose solution (table sugar) with that of clumps of yeast cells, formed naturally when the cell walls of the yeast failed to fully separate during cell division. They found that the cells in clumps continued dividing, an indication they were eating well and growing normally, while single cells in the same solution did not divide.

Butcher reportedly described the BlackBerry Messenger service as "text messaging with steroids."

The $1.1 billion Juno mission will also allow humans to see below Jupiter's dense cloud cover for the first time. It will also capture color images of Jupiter's cloud tops in visible light as a way of engaging the public, who will be involved in helping design which areas of Jupiter should be imaged.

thebchuckster writes: The African crested rat has been known to kill local dogs, but researchers have just figured out how. After eating the "poison-arrow plant," the oversized rodent stores its poison-laced spit in special hollow hairs in its mohawk. Then, when a predator grabs the rat, the animal gets stung with the poison and spit-tipped hairs which can sicken and kill.

thebchuckster writes: Just a few decades ago, the Yellowstone National Park in Wyoming routinely saw no big wildfires in a given year.

However, due to global warming, there will be a big wildfire virtually every single year by 2050 and the area burned will be nearly 400 square miles. By 2075, the area burned is expected to exceed 1,200 square miles. (The entire Yellowstone park spans just under 3,500 square miles.)
